1 General Specifications Model DO30G and FD30/PB30 Sensor and fittings for Dissolved Oygen DO The DO30G sensor for dissolved oygen is designed for use in water treatment plants such as sewage treatment works, effluent activated sludge process, and potable water treatment. It is also effective in river monitoring, intake protection, fish farming and other fields where water quality is important. This galvanic cell has a fast response time and good long term stability, and features replaceable diaphragm and cable for easy maintenance. A temperature sensor is incorporated for compensation. The DO30G sensor can be used in either the PB30 floating ball fitting or in the FD30 immersion fitting. The PB30 floating ball holder for the DO30G features a design which minimises fouling by the process. A brass ring around the sensor facilitates a check for membrane integrity, and helps to eliminate any deposits of algae, making a cleaning system unnecessary for the model PB30. Maintenance is very simple, with only periodic inspection and calibration needed. The FD30 PVC immersion fitting is designed for installing the DO30G sensor in tanks, open vessels and drains. It can be supplied in lengths between 0.5 and 2.0 meter. Flange mounting is also possible. In applications with a heavy load of solids the use of a cleaning system is recommended, so an option, a jet cleaner is available for the immersion fitting. The use of this device can etend the continuous measurement period and eases maintenance.

2 2 DO30G Sensor The DO30G sensor, which replaces the previous model DOX8SM, is the heart of Yokogawa s Dissolved Oygen measuring loop. It can be supplied with membrane thicknesses of 25 or 50 µm. The detachable connection cable comes in 5 different lengths between 3 meters and 20 meters. For convenience both the cell assembly and the cable are available as spare parts, as are the membrane sets and O-rings.

4 4 FD30 Immersion Holder Intended to mount the sensor in tanks, the immersion fittings should be installed where the point of measurement truly represents the entire solution. Avoid areas where the measurement value varies significantly e.g. stagnant corners. Select a place where the sensor is always immersed in the process liquid. The FD30 fitting is standard equipped with membrane check-facility and can be specified with or without a flange. Cable length and sensor membrane can also be specified in the MS code. For types without a flange, a mounting set and a jet cleaner are available as options. /JC Jet Cleaner This optional cleaner gives the opportunity to avoid build up of deposits and consequent fouling on the sensor membrane. This is achieved by spraying water (or air) onto the membrane of the DO-sensor. The spray head is equipped with a built-in (non-return) valve to avoid penetration of the process liquid into the cleaning system. The EXA DO400 has a built-in wash timer with programmable washtime, interval time and recovery time for the automatic cleaning of the sensor.

6 6 PB30 Floating Ball The design of the PB30 floating ball ensures minimum user maintenance. The constant movement of the ball with the action of waves on the surface of the tank provides a good flow of sample at the membrane surface. Constant measurement depth is also assured. The solution ground ring in brass, gives the facility of a membrane check, while also minimising algae growth on the sensor. For convenience, the PB30 includes a winch mounting mechanism, and is normally specified as a unit complete with sensor and cable.
